Three different models of inservice nutrition education implemented by Detroit's Nutrition Education Training (NET) Project are described and compared. The NET Project was funded first as a pilot project in 1978-79, and was refunded in 79-80 and 80-81. The original pilot project goal was to demonstrate the value of teaching urban day care staff members to provide hands-on, classroom food activities for the preschoolers in their care. The Year I Model provided intensive, on-site training in six workshops focused on topics such as food attitudes, nutrition facts, and mealtime procedures in the center. The goal in the Year II model was to develop a less expensive model so that several centers could receive on-site training. Experience showed that (1) the Year I Model could not be reduced to one session and that (2) the original emphasis on classroom activities was of secondary importance: first priority had to be given to upgrading mealtime and nutrition at the 10 participating centers. In the third year, on-site training was impossible because of reduction in funds. Therefore, a 2 1/2-hour nutrition session was presented as part of a 20-hour training experience in the Michigan Day Care Provider Training Project. Comparison of the three models leads to the conclusion that the most relevant inservice intervention uses the mealtime situation as learning occasions for the children. (RH)
